This application is a continuation application of U.S. application Ser. No. 16/169,016 filed on Oct. 24, 2018, which claimed priority from China Patent Application Serial Number 201721592267.X, which was filed on Nov. 24, 2017, the entire content of which is herein incorporated as reference.

BACKGROUND OF THE INVENTION 1. Technical Field

The present application present application relates to field of external doors and windows of buildings, and in particular, relates to an energy-saving security composite window.

2. Background Art

At present, aluminum alloy windows and plastic-steel windows are widely used in China. Aluminum alloy profiles that are mainly used by the aluminum alloy windows are hollow aluminum alloy profiles with wall thickness equal to or greater than 1.4 mm. Key fabrication procedures of doors and windows are corner combination and assembly. According to a main process of the corner combination, connections between corners of door and window frames and sashes, and connections between a side frame and a muntin are mostly achieved by riveting, corner brace combination, or screw connection. The connection manner is used for connecting a hollow metal with another hollow metal, which cannot effectively ensure overall performances of doors and windows such as sealing, strength, heat insulation, and sound insulation nor effectively prevent heat conduction between indoors and outdoors to reduce running time of household temperature-controlled appliances, eventually resulting in severe energy waste. Usually, three-cavity or multi-cavity PVC plastic profiles with a wall thickness equal to or greater than 2.2 mm are used for the plastic-steel windows, where one cavity is provided with a reinforced steel liner with a wall thickness being 1.5 mm. The corners of door and window frames, a side frame and a muntin are welded together by hot melting plastic profiles, which achieves only connection of the plastic profiles rather than perform any connection for the reinforced steel liners in the cavity. With this process, the overall strength of the doors and windows is greatly reduced, and the doors and windows are easy to deform, thereby leading to poor anti-wind pressure performance, poor anti-warping performance, poor anti-destruction performance, and shorter service life.

SUMMARY OF THE INVENTION

The present application provides a composite window integrating energy-saving, security, sound insulation, superior anti-wind pressure performance and long service life.

The window based on the present application comprises:

a peripheral side frame and glass installed on the side frame. The side frame is of a composite structure comprising:

a metal pipe located centrally to serve as a main body of the side frame and having an inner cavity filled with a filling material;

The glass may be laminated hollow multi-layer glass. A glass padding block may be placed at a position that is on the bottom of the glass and is in contact with the rectangular high-strength metal pipe.

The filling material may be a polyurethane foam heat insulation material.

The metal alloy profile may be fixed at an angle of 90 degrees or a flat angle or an angle of 45 degrees at a corner of the side frame or at a connection of the side frame and the muntin. The rectangular high-strength metal pipe may be welded at an angle of 90 degrees or a flat angle or an angle of 45 degrees at a corner of the side frame or at the connection of the side frame and the muntin.

The connections of the rectangular high-strength metal pipe and the metal alloy profile at the corner of the side frame may be both straight seam connections, connecting seams of which are perpendicular to each other.

The connections of the rectangular high-strength metal pipe and the metal alloy profile at the connection of the side frame and the muntin may be both straight seam connections, connecting seams of which are perpendicular to each other or paralleled to each other in a staggering way.

The external profile may be fixed solely on an outer surface of the non-metal profiles or both on the outer surface of the non-metal profiles and an outer surface of the metal pipe.

The double cavity structure is adopted in the example.

There are a plurality of the non-metal profiles 4 (8) which are respectively fixed on an outer surface of the rectangular high-strength metal pipe 5 and an installation groove for the laminated hollow multi-layer glass 1 is formed between the rectangular high-strength metal pipe 5 and the non-metal profile 4(8); the non-metal profile 4(8) is a polymer material such as a PVC plastic material and a wooden material; the non-metal profile 4(8) is of a solid structure, a single cavity structure, a double cavity structure or a multi-cavity structure, for example, the non-metal profile 4 is of a multi-cavity structure and the non-metal profile 8 is of a single cavity structure.

The metal alloy profile 2 may be fixed solely on an outer surface of the non-metal profiles 4(8) or both on the outer surface of the non-metal profiles 4(8) and that of the rectangular high-strength metal pipe 5. The multiple non-metal profiles are respectively fixed on the outers surface of the rectangular high-strength metal pipe 5, but maybe not necessarily cover the entire outer surface of the rectangular high-strength metal pipe 5. Therefore, there are two situations of fixing the metal alloy profile 2. For example, FIG. 2, right part, shows the first way of fixing the metal alloy profile 2, i.e., fixing it solely on an outer surface of the non-metal profiles 4(8), and FIG. 2, left part, shows the second way of fixing the metal alloy profile 2, i.e., fixing it both on the outer surface of the non-metal profiles 4(8) and that of the rectangular high-strength metal pipe 5.

First, rectangular-shaped lug 2 b-ii (plug) is snapped into rectangular U-shaped slot 2 a-i to form one end (plug end) that completely combines 2 a and 2 b. Further, via buckle installation, hook claw male buckle of 2 b-i and female buckle 4-i of slot fit to form an internal hidden buckle. The hook claw has only a leading in angle but not a leading out angle. Once buckled, the connecting part forms an internal hidden buckle, therefore achieving self-locking state, which is not easy to disassembly.
